What is insulin?

Insulin is a pancreatic hormonal secretion produced by beta cells. As a type of anabolic hormone, it generates the metabolism of different macromolecules like fats, carbohydrates, and proteins. It also helps in the absorption of glucose from blood vessels and transports them into fat, liver, and skeletal muscle cells. These tissues then convert it to another form called glycogen or fats.

 

The high concentration of insulin in the blood inhibits glucose production, especially by liver cells, whereas its low concentration in blood enhances catabolism.
